Use of pericholedochal plexus for portal flow reconstruction in diffuse portal vein thrombosis: case report

Portal vein thrombosis (PVT) remains a challenging issue for liver transplantation surgeons. Most patients who have PVT undergo eversion thrombectomy. When thrombectomy is not successful due to diffuse PVT, other modalities are adapted, such as the use of a venous jump graft or portal tributaries. Here, we report our successful experience with reconstruction of portal flow using collateral plexus for a patient with grade 4 PVT. Thrombectomy did not restore portal flow. A pericholedochal plexus was found on the lateral wall of common bile duct. Direct end-to-end anastomosis was performed between the donor's portal vein and patient's choledochal plexus. Postoperative color Doppler ultrasound revealed normal portal flow.
